I want to use Windows 10 (64bit) and Ubuntu 18 with dual-boot on my Thinkpad X380 Yoga. (This is my first move into the direction of linux and the first time I am installing an OS by myself)
First installed Windows 10 without any problems. Then I read in the manual https://download.lenovo.com/pccbbs/pubs/x380yoga_s1_4th/html_en/index_en.html#Installing_the_Windows_10_operating_system_(topic)_T0000574679 that I should have enabled "OS Optimized Defaults" before installing windows.
In my case "OS Optimized Defaults" was disabled.
I changed "OS Optimized Defaults" to be enabled after the windows installation and windows is still booting.
Now I want to install Ubuntu 18.04 on the unused partition.
Should I enable or disable the "OS Optimized Defaults" option? What does "OS Optimized Defaults" actually mean? What are the pros and cons of the two options.
On https://support.lenovo.com/at/de/downloads/ds033268 there is an explanation for "OS optimized Defaults", but I don't know anything about the difference between BIOS and UEFI.
By googling I found an old article that tells that choosing the wrong option for "OS Optimized Defaults" could brick your system. This only scared me more than it helped me to find out what this "OS Optimized Defaults" is all about.
